In this demo, Festo’s Alejandro López demonstrates how system integrators and machine builders might utilize cobots from different manufacturers in a seventh-axis application.
Seventh-axis robots refer to robots on an electromechanical linear actuator that can move horizontally and vertically. The addition of a linear rail in effect extends the reach of a six-axis robot.
Lopez explained the productivity and cost advantages of moving the robot closer to the payload. The use of smaller six-axis robots means lower acquisition costs and a more compact footprint, he said.

The demo also showcased the Festo Motion Control Package (FMCP) panel controls turntables, automatic storage systems, conveyors and transfer tables. The FMCP is configured to allow wall mounting and supports future expansion.
Adaptive Grippers
The way parts are handled has a direct impact on productivity in automated manufacturing and assembly processes. Vacuum technology or gripper technology can handle a range of materials and parts. Festo’s picking and placing solutions include the adaptive shape gripper DHEF, the adaptive finger gripper DHAS and vacuum gripping solutions.
In the demo, Lopez was able to control the gripper with a tablet. He said a VPPI actuated valve can be controlled via analog signal, which allowed him to adjust the pressure needed to handle delicate parts. The FDA-approved gripper can handle eggs and other food items as well as glass (including lightbulbs).
“This is very unique in the market,” Lopez said.
